Ian Jackson: chiark’s skip-skip-cross-up-grade
https://diziet.dreamwidth.org/11840.html
July 19, 2022, 7:43 PM
Two weeks ago I upgraded chiark from Debian jessie i386 to bullseye amd64, after nearly 30 years running Debian i386. This went really quite well, in fact!
Background
chiark is my “colo” - a server I run, which lives in a data centre in London. It hosts ~200 users with shell accounts, various websites and mailing lists, moderators for a number of USENET newsgroups, and countless other services. chiark’s internal setup is designed to enable my users to do a maximum number of exciting things...

Russell Coker: DDC as a KVM Switch
https://etbe.coker.com.au/2022/07/19/ddc-switch/
July 19, 2022, 11:55 AM
With the recent resurgence in Covid19 I’ve been working from home a lot and using both my work laptop and personal PC on the same monitor. HDMI KVM switches start at $150 and I didn’t feel like buying one. So I wrote a script to change inputs on my monitor. The following script locks the session on the local machine and switches the monitor’s input to the other machine. I ran the command “ddcutil vcpinfo| grep Input” which shows that (on my monitor at least) 60 is the VCP for input. T...

Martin-Éric Racine: Trying to chainload iPXE on old Etherboot hardware
http://q-funk.blogspot.com/2022/07/trying-to-chainload-ipxe-on-old.html
July 17, 2022, 7:10 PM
Among my collection of PC hardware, I have a few rarities whose netboot implementation predates PXE. Since I recently managed to configure dnsmasq as a potent TFTP and PXE server, I figured that I'd try chainloading iPXE via BOOTP options. This required preparing a boot image using antiquated tools:
$ sudo mkelf-linux --param=autoboot --output=/srv/tftp/ipxe.nbi /srv/tftp/ipxe.lkrn
The host succesufully loads the boot image, except that the iPXE blob fails to find the network card:

Petter Reinholdtsen: Automatic LinuxCNC servo PID tuning?

While working on a CNC with servo motors controlled by the
LinuxCNC
PID
controller, I recently had to learn how to tune the collection of values
that control such mathematical machinery that a PID controller is. It
proved to be a lot harder than I hoped, and I still have not succeeded
in getting the Z PID controller to successfully defy gravity, nor X
and Y to move accurately and reliably. But while climbing up this
rather steep learning curve, I discovered that some motor control

I arrived in Prizren late on Wednesday. Here’s what I did during debcamp (so over 3 days). I hope this post just motivates others to contribute more to Debian.
At least 2 DDs want to upload packages that need a new version of python3-jsonschema (ie: version > 4.x). Unfortunately, version 4 broke a few packages. I therefore uploaded it to Experimental a few months/week, so I could see the result of autopkgtest reading the pseudo excuse page. And it showed a few packages broke. Here’s th...

Recently I've been working with simple/trivial scripting languages, and I guess I finally reached a point where I thought "Lisp? Why not". One of the reasons for recent experimentation was thinking about the kind of minimalism that makes implementing a language less work - being able to actually use the language to write itself.
FORTH is my recurring example, because implementing it mostly means writing a virtual machine which consists of memory ("cells") along with a pair of stacks, and some...

I’ve been wanting to use my brand new NitroKey 3, but TOTP is not supported yet. So, I’m looking to implement it myself, since firmware and tooling are open-source.
NitroKey 3’s firmware is based on Trussed framework. In essence, it’s been designed so that anyone can implement an independent Trussed application. Each such application is like a module that can be added to Trussed-based product. So if I write a Trussed app, I’d be able to add it to NK3’s firmware....

This means that given the default firmware configuration, nothing other than Windows will boot. It also means that you w...

Given news that ISC's DHCP suite is getting deprecated by upstream and seeing how dhclient has never worked properly for DHCPv6, I decided to look into alternatives. ISC itself recommends Roy Maple's dhcpcd as a migration path. Sadly, Debian's package had been left unattended for a good 2 years. After refactoring the packaging, updating to the latest upstream and performing one NMU, I decided to adopt the package.

Server setup
The first thing I did was to open up my server's

remote connections since it's going to be the destination host for the
router's log messages.

Tim Retout: Git internals and SHA-1
https://retout.co.uk/2022/06/29/git-internals-and-sha1/
June 29, 2022, 5:54 PM
LWN reminds us that Git still uses SHA-1 by default.
Commit or tag signing is not a mitigation, and to understand why you need to
know a little about Git’s internal structure.
Git internally looks rather like a content-addressable filesystem, with four
object types: tags, commits, trees and blobs.
Content-addressable means changing the content of an object changes the way
you address or reference it, and this is achieved using a cryptographic hash
function. Here is an illustration of the inte...

Russell Coker: Philips 438P1 43″ 4K Monitor
https://etbe.coker.com.au/2022/06/29/philips-438p1-43-4k/
June 29, 2022, 12:00 PM
I have just returned a Philips 438P1 43″ 4K Monitor [1] and gone back to my Samsung 28″ 4K monitor model LU28E590DS/XY AKA UE590.
The main listed differences are the size and the fact that the Samsung is TN but the Philips is IPS. Here’s a comparison of TN and IPS technologies [2]. Generally I think that TN is probably best for a monitor but in theory IPS shouldn’t be far behind.
The Philips monitor has a screen with a shiny surface which may be good for a TV but isn’t good for a monit...

Michael Ablassmeier: More work on virtnbdbackup
https://abbbi.github.io//virtnbdbackup-blog/
June 29, 2022, 12:00 AM
Had some time to add more features to my libvirt backup utility, now it
supports:
Added backup mode differencial.
Save virtual domains UEFI bios, initrd and kernel images if defined.
virtnbdmap now uses the nbdkit COW plugin to map the backups as regular
NBD device. This allows users to replay complete backup chains
(full+inc/diff) to recover single files. As the resulting device is
writable, one can directly boot the virtual machine from the backup
images.

Dima Kogan: vnlog 1.33 released
http://notes.secretsauce.net/notes/2022/06/28_vnlog-133-released.html
June 28, 2022, 4:47 PM
This is a minor release to the vnlog toolkit that adds a few convenience options
to the vnl-filter tool. The new options are
vnl-filter -l
Prints out the existing columns, and exits. I've been low-level wanting this for
years, but never acutely-enough to actually write it. Today I finally did it.
vnl-filter --sub-abs
Defines an absolute-value abs() function in the default awk mode. I've been
low-level wanting this for years as well. Previously I'd use --perl just to
get abs(), or I'd...

Jonathan Dowland: WadC 3.1

Example map with tuneables on the right
WadC — the procedural programming environment for generating Doom
maps — version 3.1 has been released. The majority of this was done
a long time ago, but I've dragged my feet in releasing it. I've said
this before, but this is intended to be the last release I do of WadC.
The headline feature for this release is the introduction of a tuning
concept I had for the UI. It occurred to me that a beginner to WadC
might want to load up an example progra...

Jamie McClelland: Deleting an app won't bring back Roe v Wade
https://current.workingdirectory.net/posts/2022/dont-panic-organize/
June 25, 2022, 10:27 PM
In some ways it feels like 2016 all over again.
I’m seeing panic-stricken calls for everyone to delete their period apps, close
their Facebook accounts, de-Google their cell phones and, generally speaking,
turn their entire online lives upside down to avoid the techno-surveillance
dragnet unleashed by the overturning of Roe v. Wade.
I’m sympathetic and generally agree that many of us should do most of those
things on any given day. But, there is a serious problem with this cycle of
repressio...

Ryan Kavanagh: Routable network addresses with OpenIKED and systemd-networkd
https://rak.ac/blog/2022-06-25-routable-network-addresses-openiked-systemd-networkd/
June 25, 2022, 11:41 AM
I’ve been using OpenIKED for some time now to configure my VPN.
One of its features is that it can dynamically assign addresses on the internal network to clients, and clients can assign these addresses and routes to interfaces.
However, these interfaces must exist before iked can start.
Some months ago I switched my Debian laptop’s configuration from the traditional ifupdown to systemd-networkd.
It took me some time to figure out how to have systemd-networkd create dummy interfaces on which...

Kees Cook: finding binary differences

June 24, 2022, 8:11 PM
As part of the continuing work to replace 1-element arrays in the Linux kernel, it’s very handy to show that a source change has had no executable code difference. For example, if you started with this:
struct foo {
unsigned long flags;
u32 length;
u32 data[1];
};
void foo_init(int count)
